Diversity of Extinct and Living Actinistian Fishes (Sarcopterygii)
Environmental Biology of Fishes, 1991A total of 121 actinistian species belonging to 47 genera and 17 undetermined actinistians is reported from the literature. There are 69 valid species with fair assessment of their phylogenetic position; 21 valid species with poor assessment of their phylogenetic position; 31 actinistian incertae sedis; and 18 taxa that had been identified incorrectly ...

IV SARCOPTERYGII, Fleischflosser
2014Unter den rezenten und fossilen Fischen sind die Sarcopterygier durch fleischige Loben an den paarigen Flossen charakterisiert. Fossil gehen sie bis in das Obere Silur (vor 420 Mio. Jahren) zuruck.

The oldest known stegocephalian (Sarcopterygii: Temnospondyli) from Spain
Journal of Vertebrate Paleontology, 2006ABSTRACT More data are provided on the recently described temnospondyl Iberospondylus schultzei from the Upper Carboniferous (Stephanian C) of the Spanish Puertollano Basin. It represents the only known occurrence of a Paleozoic stegocephalian in a Spanish basin.

Recognizing lungfish (Sarcopterygii, Dipnoi) estivation burrows: ichnotaxonomy and paleoenvironment. Lungfishes first appeared on Earth around 350 million years ago in freshwater environments from Gondwana, since when they suffered harsh adaptations through the geological time, among which, the aestivation capability. Such a behavior keeps preserved in

NEW ONYCHODONTIFORM (OSTEICHTHYES; SARCOPTERYGII) FROM THE LOWER DEVONIAN OF VICTORIA, AUSTRALIA
Journal of Paleontology, 2007Abstract The Onychodontiformes is a poorly known sarcopterygian fish group, with four genera currently described, predominantly from the Middle-Late Devonian. A new onychodont, Bukkanodus jesseni n. gen. and sp., from the Fairy Formation, Victoria, Australia, is of Early Devonian (mid-late Pragian) age, representing one of the oldest known occurrences ...

First record ofPorolepis(Sarcopterygii; Porolepiformes) from eastern Gondwana
Canadian Journal of Earth Sciences, 2013Porolepiformes (Sarcopterygii) are poorly represented in the Devonian of Australia and eastern Gondwana as a whole. New cosmine-covered lower jaws from the Mulga Downs Group, western New South Wales (?Pragian–Emsian or Eifelian), represent the first occurrence of Porolepis in Australia, a genus formerly known exclusively from the Northern Hemisphere ...

Sarcopterygii and the Origin of Tetrapods
1977The affinities of land vertebrates have been discussed many times, the history of the issue in itself being an interesting subject. It is not necessary at the moment to go into details; let us only recall that the important paper of Jarvik (1942), as well as the long series of later publications by this author (e.g.

Geobios, 1995
Abstract In northern France and Belgium; Palaeozoic sarcopterygians are represented by actinistians (six species of Rhabdoderma ranging from the Visean to Westphalian D); onychodontids (remains of Onychodus from the Givetian to the middle Frasnian); dipnoans (four genera including 11 species ranging from the Givetian to the Famennian); porolepiforms (
